The Houston Astros pitching staff has been on a tear recently, leading this team to the second-best record in MLB in the past 15 days — tied with the Tampa Bay Rays at 9-4. The Astros sit comfortably on the top of the American League West with a 42-31 overall record. During this stretch, the pitching staff is leading the entire Majors in strikeouts with 147 — nine more than the second-place Atlanta Braves and 20 more than the third-place Baltimore Orioles. This is a huge reason why their WHIP of 1.05 is second in the MLB and leads the AL.
